ATMEGA128-16AU Datasheet – 8-bit Microcontroller – ATMEL

Part Number: ATMEGA128-16AU

Function : 8-bit Microcontroller with 128K Bytes In-System Programmable Flash

Package: 64-lead TQFP

Manufacturer: ATMEL Corporation




The high-performance, low-power Atmel 8-bit AVR RISC-based microcontroller combines 128KB of programmable flash memory, 4KB SRAM, a 4KB EEPROM, an 8-channel 10-bit A/D converter, and a JTAG interface for on-chip debugging. The device supports throughput of 16 MIPS at 16 MHz and operates between 4.5-5.5 volts.

By executing instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed.
